We just got our new home recently and were looking for a furnace, humidifier and an air-conditioning unit.We did lot of shopping around to get the best stuff as well as for the best price. I came across Cosmopolitan Mechanical services who were confident to give me a written guarantee on price and workmanship. The confidence to deliver the best service at the lowest price made me think of giving them a chance and I bet you they kept up to their word. I got the best available goods and the best service. Till date everything is working just fine and from time to time I get follow up calls to make sure the equipment is functioning efficiently. I would defintely recommend them to anybody who is thinking about installing a new heating or cooling unit in their homes. They also provide excellent service at any time of the day. I would say they deserve three thumbs up for their excellent quality and service.
